Same, of which the following is a specilioa-' tion.

The production from tobaccostems and other tobacco waste of paper suitable for use as wrappers for cigars, cigarettes, and other purposes has been hitherto attempted or'suggested, and although such a product is very desirable and although many stems are prac tically wasted these attempts and suggestions have until now proven commerciallyuni'ruitful.

One object of the present invention is to obviate the defects and disadvantages heretofore encountered and to provide asatisfactory and capable tobacco paper for suchuses and alsoa method of making or preparing the same. i

In the present invention the paper is made from the fibrous parts of the toinmco-stenns freed from the cellular and extractive .matter, and therefore is better than if the cello lar matter were present, because it requires no binder and is quite strong and is also bet-' -ter than if the extractive matter were present,

because the latter contains potash, which is undesirable, and also an excess of saltpeter and also other noxious or undesirable materials. Moreoveiyin myinvention the extractive matter is purified or freed from such ingradients before its application to the paper, so that the taste, odor, quality, and way of burning the latter are unobjectiouable.

Topractice the invention, tobacco-stems in their natural condition-that is, without being comminuted-are subjected for two or three hours, more or less, to the action of steam at eighty pounds pressure, more or less, and water. This may be accomplished in a closed vessel, such as a pnlp-digest-er. The purpose of this is to loosen the cellular in respect to the fibrous tissue and to extract juice, saltpeter, potash, fusel-oil, tannin, and

other chemicals and matters, all of which, singly or collectively; with the exception of the cellular matter, are hereinafter referred to by the term extractive matter. The

mass is further treated by straining to sep-' arate the cellular material and squeezing or the like to eliminate the extractive as well as other matter, leaving substantially only the fibers. During this operation combing or rolling and washing may be resorted to, the purpose being, as stated, to obtain the fibers freed from cellular matter and from extractive matter of an undesirable kind and in a good long and strong condition. The fibrous part may be treated by a repetition or repetitions of the described operation. The fibers so treated are then pnlped and made into paperfor exampl,-by beating them up with water, as in a rotary beater, and forming them as on gauze or bringing them into sheet form, which sheets may be calendered, or, if desired, embossed, to look like the'markings of the natural leaf. If desired, from one to two per cent, by weight, of glycerin and from one -half per cent. to one per cent, by weight, of licorice may be added to-the pulp. The purpose of the glycerin is to improve its consistency or structure and'of the licorice to flavor it. To color the paper and to add to it the qualities possessed by natural tobacco-leaves, such as are used for wrappers, the. pulp is'impregnated or reinfused with a liquor prepared by treating the solution or juice derived from the boiling or digesting operation or operations. It is obvious that the same result would be accomplished by staining or impregnating the paper itself. Some of the qualities referred to are an even retarded burning and the exhibiting of a grayish ash. For the purpose of reinfusing or impregnating the pulp or'paper the extractive solution, from which the cellular and solid matter may be strained, is heated under pressure in a closed receptacle to a temperature exceeding 250Fahrenheit, so as to drive off fusel-oil and any other volatile constitcent which will go cit at'that temperature. The pressure is then suddenly relieved and the fusel-oil. and water blown over in the form of steam or vapor. of the fusel-oil in the manner stated the extractive matter is usually left comparatively dry, and it may sometimes become necessary to add water to takethe place of that which went over with the fusel-oil.
